LEG AND SOCKET CONSTRUCTION.

Specification of Letters Patent.

Patented July 25, 1916.

To all whom it may concern:

Be it known that we, ERNST E. Prnrrnn and FRANK Prnrrrnncitizens of theUnited States, and residents of, respectively, Milwaukee, in the countyof Milwaukee and State of lVisconsin, and Chicago, in the county of Cookand State of Illinois, have invented new and useful Improvements in Legand Socket Construction, of which the following is a description,reference being had to the accompanying drawings, which are a part ofthis specification.

This invention relates to improvements in leg and socket constructionmore particularly adapted for wash tubs, wash stands and other likepurposes, for supporting said objects a convenient distance above thefloor.

It is one of the objects of the present invention to provide a leg andsocket construction which may be easily formed of rolled or drawncommercial metal in a very simple manner.

A further object of the invention is to provide a leg and socketconstruction in.

which the socket member may be permanently attached to the object to besupported and the leg may then be removably inserted in the socket.

A further object of the invention is to provide a leg and socketconstruction in which the socket member serves to reinforce the side andbottom portion of the receptacle to which it is attached.

A further object of the invention is to provide a leg and socketconstruction which is of simple construction, is strong and d11- rableand may be manufactured for a mini mum cost.

With the above and other objects in view the invention consists of theimproved leg and socket construction and its parts and combinations asset forth in the claims and all equivalents thereof.

In the accompanying drawings in which the same reference charactersindicate the same parts in all of the views: Figure 1 is a side view ofaportion of a tub provided with the improved leg and socket construction;Fig. 2 is a vertical sectional view thereof; Fig. 3 is a transversesectional view taken on line 3-3 of Fig. 1; Fig. 4: is a side view of atub provided with a modified form of leg and socket; Fig. 5 is avertical sectional view thereof; Fig. 6 is a transverse sectional viewtaken on line 0-6 of Fig. l;

Fig. 7 is a side view of a portion of a tub provided with anothermodified form of leg and socket; Fig. 8 is a sectional view thereof; andFig. 9 is a sectional detail view taken on line 99 of Fig. 7.

Referring to the drawing the numeral 10 indicates a metal washtub orother suitable receptacle to which is secured a number of the improvedleg and sockets, usually three or four. The tub or like receptacle is ofordinary construction and is provided with circumferential side andbottom corrugations 11 and 12 and with an annular bead 10 which projectsbelow and outwardly from the lower edge of the tub. lVhile the improvedlegs and sockets may be of various cross sectional shapes, such asangles, channels, T-shapes, it is only thought necessary to show anddescribetwo or three of the preferred forms.

The invention contemplates forming the legs of commercial rolled ordrawn metal cut to proper lengths and forming socket members to fit thedifferent cross sectional shapes of the legs. In the first form shownthe socket member 13 is constructed of a strip of sheet metal bent toform attaching side flanges 1d and a socket or opening 15 extendingvertically therethrough of T-shape in cross section. In forming thesocket and the side flanges let the side portions of the strip arefolded over to form the said flanges of double thickness and are thenbent and spaced from the back portion 16 to form the T-shape socket withthe side edge portions 17 of the strip jointed together medially,longitudinally of the socket member by rivets 18. The back portion 16 ofthe socket member is corrugated as indicated by the numeral 19 for aportion of its length to offset the said portion from the tub a slightdistance and the other parts are shaped to fit the tub or otherreceptacle. The back portion of said socket member is extended above andbelow the socketed part to provide additional attaching portions. Thelower extension 20 is bent approximately at right angles to extendbeneath the bottom portion of the tub and is slightly corrugatedtransversely to fit the corrugated bottom portion of the tub and theannular bead 10' thereof. The upper extension 21 is also transverselycorrugated to fit the side corrugations of the tub and both theextensions and the main portion of the back are socurely fastened to theback by rivets 22 or other means.

A leg member 23 formedof a piece of commercial T-iron cut to length andslightly angled at a point 23 to incline the leg outwardly is providedwith a stop projection in the form of an angled bar 2st which is rivetedto the inner side of the leg member with the angled portion 24projecting inwardly beneath the tub and bearing against the corrugatedportion of the angular lower extension 20 of the socket member. In orderto lock the leg within the socket a portion 25 of the stem of theT-shaped leg is bent over at right angles and provided with a threadedopening to receive a thumb screw 26. The thumb screw. 26 is threadedthrough said opening and impinges against the bent over portion of thesocket member and securely locks the parts'together. The portion of thesocket member which receives the bent over portion of the leg member isslotted and the' side portions 17 are omitted as indicated by thenumeral 27 to accommodate said bent over portion.

In the form shown in Figs. 4, 5 and 6 the socket member is preferablyformed of a strip of" metal in which the side; flanges 28 are of singlethickness ofmetal and opposite interposed side portions 29 are foldedover toward each other toform a socket to receive the side flanges 30 ofthe T-shaped leg 23 and to form a slot 31 to accommodate the stemportion 32 of said leg. In this form the leg is locked in position inthe same manner before described and is furthermore provided with anadditional looking screw bolt 26 which is threaded through a bent overportion 25 similar to the portion 25 but bent in the opposite direction.

The modified form shown in Figs. 7 8 and 9 provides for using a legmember formed of a flat bar 33 and the socket member 84 isbentsimilar-to the first mentioned form with the exceptionthat the space foraccommodating the stem of the first mentioned leg member is omitted andthe space or socket 35 formed is approximately rectangular in crosssection. In this last mentioned form the locking thumb screw 36 isthreaded through the leg member and its shoulder 86 clamps against thebent over metal on each side of the slot 27. In other respects the legand socket member parts are the same as before described.

From the foregoing description it will be seen that the leg and socketconstruction is of simple form and is welladapted for the purposedesired and it will also be seen that the leg members may be easilyremoved if desired and the tubs used'in the ordinary manner.

What we claim as ourinvention is:

1. A leg and socket construction formed of commercial strip. metal,comprising a socket member formed of a strip of metal bent to formattaching side flanges and a socket extending therethrough of T-shape incross section, and a leg member of T- shape in cross section fittinginto said socket,
